Awww, he's a little sweetiepie!!! What a soulful, sweet little face! I, like the others, don't think he is purebred but he sure looks to be part Yorkie from his coloring and other aspects. His muzzle is a bit long, his ear leather quite thick, ears lowset and floppy, his head not quite as tall as a Yorkie pup's would be and his coat sparser on his head not nearly as teddybear fluffy overall as most 2 mos. old Yorkie pups I've seen. But he's got several other things that do give a Yorkie look. I'll tell you, that little boy has one beautiful little face and expression. Is he calm? He looks so calm and composed in those pictures. I'll bet he's going to make one sweet companion and pet if he's half as sweet and loveable as he looks.
Welcome to YorkieTalk and good luck with the puppy stage! It's going to be trying at times and your dog is awfully, awfully young to leave its mother so be prepared to be kind of a nursemaid as he mourns missing and being parted to early from her. He'll likely moan and carry on at bedtime if he can't be quite near you as he's a canine and canines are pack animals and sleep together in family heaps, either piled on or very near one another for warmth and safety.
He doesn't look like a tiny dog but a young pup can become hypoglycemic so look up the symptoms of hypoglycemia and be prepared to coat his gums with Nutrical, local honey or Karo Syrup should he get lethargic or wobbly, shaky, disoriented, etc., as you head for the vet.
Here is a good link to read from our YT Library, the Puppy Care and Puppy Info Library, and it is a thread all about care of the Yorkshire Terrier puppy.
